速度矢量滚转定义为飞机在保持定常迎角的情况下,围绕其瞬时速度矢量所产生的无侧滑、速度保持为常值的旋转运动。对于典型的战术飞机,最大俯仰力矩是飞机方位的函数,在水平轨迹中出现在倾斜90°的情况,此时飞机的滚转速率达到峰值,迎角超过45°。最大滚转力矩依赖于滚转模态时间常数。对于较小的滚转时间常数(快速响应),最大滚转力矩出现在最大滚转加速度、零迎角,基本与飞机的方位无关;对于较大的滚转时间常数,最大滚转力矩出现在最大滚转速率、迎角最大、倾斜角180°的水平飞行中。最大的航向力矩出现在最大滚转加速度、迎角最大时,基本与飞机的方位无关。
Velocity vector roll is defined as the rotation of the aircraft with no side slip and its speed maintained constant around its instantaneous velocity vector while maintaining a steady angle of attack. For a typical tactical aircraft, the maximum pitch moment is a function of the aircraft’s azimuth, appearing at a 90 ° tilt in the horizontal trajectory, at which point the airplane’s roll rate peaks and the angle of attack exceeds 45 °. The maximum roll moment depends on the roll mode time constant. For smaller roll time constants (fast response), the maximum roll moment occurs at the maximum roll acceleration, zero angle of attack, basically independent of the orientation of the airplane; for larger roll time constants, the maximum roll moment occurs at Maximum roll rate, maximum angle of attack, tilt angle of 180 ° horizontal flight. The maximum heading torque appears at the maximum roll acceleration, maximum angle of attack, the basic position of the aircraft has nothing to do.
